Answer:
12.3 mph
Step-by-step explanation:
17.9 - 5.6 = 12.3
B. 0.930 ~Apex ;) .....................................
The train is traveling at 165 mph
495/3=165
825/5=165
1155/7=165
1485/9=165
<span>So, L*W=A Because it is 4 cm longer, L=W+4 Because the area is 96, LW=96 Substitute to get W(W+4)=96 Multiply it out. W^2+4W-96=0 By solving the quadratic, W+12(W-8)=0 so either W+12 or W-8 is zero. The width must be positive, so the width is 8. Therefore the length is 12.
Hope this helps.</span>
